11 Introspection

Introspection permits a programmer to peek at the contents of a class
without any previous knowledge of that class. While EIEIO implements
objects on top of records, and thus everything is technically visible,
some functions have been provided. None of these functions are a part
of CLOS.

— Function: object-slots obj

Return the list of public slots for obj.

— Function: class-slot-initarg class slot

For the given class return an :initarg associated with
slot. Not all slots have initargs, so the return value can be
nil.
